REST API Get Users Parameter Confusion

REST API Get Users Parameter Confusion

I'm using the new REST API which uses OAuth2.0 tokens. Now I want to get the user whose token I'm using to make the API requests.

In the documentation for the REST Users API ( https://www.zoho.com/crm/help/api/v2/#Users-APIs ) there's a request parameter called CurrentUser. It's description says " To get the list of current CRM users". I'm confused.
Does the CurrentUser parameter return just one user (the current one) or multiple users (as its description says)?

Should I maybe be using another parameter?
